And we should also keep in mind that even at the lowest level of quantum mechanics things are deterministic only in a rather questionable and non-observable sense. I'm somehow lost how anyone can believe as firmly as Raffael in determinism nowadays. I had thought this to be an attitude of the 19th century which had more-or-less died out. But apparently it has survived (in a sufficiently far distance from physics) until today. Nicolas

Yes, I think so. What I find especially dangerous is that arguments that suggest that free will is just an illusion can change people's behavior, and make them more passive, less active in their actions: I strongly believe that if someone thinks they are fully determined makes them act differently than if they think they have a free will. This alone shows that that level can indeed have an influence on people's decisions, no matter where their actions are actually determined or not. In other words, the determination of the physical world on one's conscious actions are irrelevant, in my opinion. Physical determination is an illusion, and a pretty dangerous one, not free will.

Physical determination > is an illusion, and a pretty dangerous one, not free will. But that's not an argument that free will is real. That's an argument that believing in determinism has harmful effects, and so there are benefits to maintaining a collective delusion that people "really" have free will (whatever that means) independent of whether or not this is actually true. I don't dispute that. But it's a different argument. It makes the difference between "illusions" and "emergent property" rhetorical, not substantive. rg

Quantum randomness does not rule out the possibility of classical determinism under the right circumstances. Computers are a pretty good example of this. rg |
